Definitions

  • the present invention relates to a method for imaging bits not to be sent, i.e. so-called DTX bits a frame to be sent, especially on one in the so-called "Compressed Mode" compressed frames to be transmitted, according to the preamble of claim 1.
  • a UMTS frame (Frame) comprises 15 time slots ("slots"), within each frame in addition to the actual data, also certain system information be transmitted.
  • This system information includes in particular a known pilot bit sequence or training sequence, that of the respective receiver to estimate the channel impulse response of the respective mobile radio channel used can be a power control information in the form of a or several TPC bits ("Transmit Power Control"), through which Content controlled the transmission power of the respective receiver as well as format identification information in the form of so-called TFCI bits ("Transport Format Combination Indicator").
  • a TFCI code word is provided for each UMTS frame, which consists of there are ten initially uncoded bits, which are then followed by a (32,10) subcode of the Reed-Muller code of the second order coded and thus mapped to a total of 32 bits.
  • 32 bits are then in normal mode (in normal operation or in non-compression mode) bits no. 0 and No. 16 punctured so that the TFCI code word is only 30 TFCI bits, which then consistently with two TFCI bits to the individual time slots of the corresponding UMTS frame be mapped or distributed.
  • the Assignment such that the two most significant TFCI bits of the TFCI code word on the first within the UMTS frame sent time slot number 0 and the two least significant Bits on the last time slot sent within the frame No. 14 can be divided. Within the individual Time slots will then be the higher TFCI bit before lower TFCI bit sent.
  • the mapping or mapping of the TFCI bits of the TFCI code word on the individual time slots a frame is also referred to as "mapping".
  • punching means Registration also removing or not sending certain, especially the last, bits.
  • Compressed Mode In addition to a normal transmission of information in uncompressed Form is also a compressed form for data transmission Mode ("Compressed Mode") provided.
  • compressed Mode is the information of the respective frame in compressed form transferred to artificially in this way to generate a transmission gap while the duration of which is the absence of information sent for example for preparation of intermediate frequency measurements can be used by handover processes etc.
  • FIGS. 5A and 5B Corresponding suggestions for time slot formats in "compressed mode" have also been made for the downlink, which can be summarized by the tables shown in FIGS. 5A and 5B, FIG. 5A referring to one for the corresponding channelization or spreading codes ("channelization Codes ”) used spreading factor between 128 and 512, while Fig. 5B relates to spreading factors between 4 and 64.
  • channelization Codes channelization or spreading codes
  • Fig. 5B relates to spreading factors between 4 and 64.
  • the number N TFCI of the TFCI bits transmitted per time slot and the total number D of the TFCI bits transmitted per frame are given for a different number of the time slots or slots transmitted in the "compressed mode" , in which case a distinction is also made between type A and type B transmission.
  • the bits are distributed in descending order to the individual time slots of the compressed frame, the TFCI bits c k and then the repeated bits d k being transmitted first, ie bit c 29 ("Most Significant Bit” (MSB) of the TFCI- Code word) is transmitted as the first bit of the TFCI code word, while d 0 is transmitted as the last bit of the TFCI code word.
  • MSB Mobileost Significant Bit
  • DTX bits discontinuous transmission bits
  • the present invention is based on that described above Prior art based on the task of a method for mapping bits not to be sent onto an in propose a frame to be sent in a compression mode, with which the transmission performance and without additional effort Transmission security can be improved.
  • the excess TFCI digits in "Compressed Mode" DTX bits i.e. energy zero bits not to be filled, the one immediately following the transmission gap TFCI locations are at least partially occupied with DTX bits.
  • the DTX bits are also particularly conceivable partly on the time slots before the transmission gap and in part to the time slots following the transmission gap divide.
  • the present invention is based on the finding that in "Compressed Mode" the power control is disturbed by the transmission gap and only with increasing distance from the transmission gap. Because of this fact, the replenishment is additional TFCI digits optimized with DTX bits.
  • a (32,10) encoder 1 is supplied with uncoded TFCI bits, which are to be mapped to the respective UMTS frame.
  • the number of uncoded TFCI bits is variable and is started at the beginning of a connection by a corresponding Signaling set. However, are fewer than ten uncoded TFCI bits exist, the corresponding TFCI word padded with zeros to a total of ten bits, in which If the higher bits are set to zero.
  • the (32,10) encoder 1 encodes the TFCI word supplied to it using a (32,10) subcode of the so-called Reed-Muller code second order.
  • the structure of the corresponding (32,10) encoder 1 is such that that of the (32,10) encoder 1 TFCI code word output by a the uncoded TFCI bits controlled linear combination of ten different base sequences is formed.
  • the resulting punctured TFCI code word thus includes only 30 TFCI bits left.
  • the 30 TFCI bits are fed to a unit 3, whose task it is these bits in "normal mode” (i.e. uncompressed Transmission) or in "Compressed Mode” (i.e. with compressed transmission) the individual time slots or Assign slots to the respective UMTS frame (see Fig. 2).
  • the TFCI bits c 29 to c 12 are first distributed to the first time slots No. 0 to No. 5 and the TFCI bits c 11 to c 0 to the next time slots No. 9 to No. 12. After all the TFCI bits of the punctured TFCI code word have thus been divided, the TFCI bits c 11 , c 10 , c 09 are repeated in time slot No. 13 and the originally punctured TFCI bits c 30 and c 31 are repeated on the last time slot No. 14 shown and the TFCI bit c 08 repeated in time slot No. 14.
  • This approach is advantageous because it is better that send formerly punctured bits of the TFCI (32,10) code word, as bits to be repeated, which are due to the "Compressed Mode "existing transmission gap under with regard the power control bad conditions have been sent.
  • the embodiment described above can also be used in this way be modified that the originally punctured bits are not placed in the last time slot of the UMTS frame, but are sent directly after the transmission gap. In addition, as in the prior art, these then become the transmission gap immediately following TFCI bits repeated. This procedure has the advantage that the bits which usually be dotted anyway on the regarding the transmission conditions "bad" TFCI digits become.
  • the TFCI bits c 29 to c 12 would first be distributed to the first time slots No. 0 to No. 5.
  • the TFCI locations of time slot No. 9 are filled with the originally punctured bits c 30 and c 31 and the TFCI bit c 11 .
  • the TFCI bits c 10 to c 2 are assigned to time slots No. 10 to 12.
  • Time slot no. 13 is occupied by the TFCI bits c 01 and c 0 .
  • the TFCI locations in time slots No. 13 and No. 14, which are then still available, are, as already described, occupied by the TFCI bits immediately following the transmission gap, so that bit c 30 in time slot No. 13 and bits c 31 , c 11 , c 10 are repeated in time slot No. 14.
  • the TFCI bits immediately following the transmission gap are repeated in reverse order in order to occupy the still free TFCI positions, ie the TFCI bits c 06 , c 07 , c 08 are repeated in time slot No. 13 and the TFCI bits c 09 , c 10 , c 11 are repeated in time slot No. 14.
  • the TFCI bits immediately following the transmission gap are repeated in reverse order and the originally punctured bits c 30 and c 31 are sent in the last time slot in order to To fill positions, ie the TFCI bits c 08 , c 09 , c 10 are repeated in time slot No. 13, while in time slot No. 14 the originally punctured TFCI bits c 30 and c 31 as well as the repeated TFCI bit c 11 be assigned to.
  • TFCI bits c 30 to c 15 , c 31 and c 24 initially relate to the first time slots No. 0 to No. 5 and the TFCI bits c 13 to c 02 the next time slots No. 9 to No. 12 will be distributed.
  • c 30 denotes bit number 0 and c 31 bit number 16 of the unpunctured TFCI code word output by encoder 1 (only the punctured TFCI code word is shown in FIG. 2).
  • the remaining TFCI bits c 01 and c 0 are first sent in time slot No. 13. The then still free TFCI locations of time slot No. 13 and time slot No.
  • the TFCI bits immediately following the transmission gap are repeated, so that in time slot No. 13 the TFCI bit c 13 is repeated, while in time slot No. 14 the TFCI bits c 12 to c 10 are repeated.
  • these DTX bits do not appear at the end of each frame excess after sending the punctured TFCI code word Distribute TFCI digits, but these DTX bits immediately after the transmission gap occurring in "compressed mode" to send. That it will be immediately after the transmission gap sent as many DTX bits as excess TFCI points are available in the frame. The remaining TFCI digits of the frame are punctured with the bits of the TFCI code word occupied.
  • This procedure has the advantage that the DTX bits be used for those TFCI offices for which the Probability of interference due to their Proximity to the transmission gap is greatest.
  • a frame is transmitted with a transmission gap comprising three time slots, this means (for example for a spreading factor of 256) according to the table shown in FIG. 5A that four TFCI locations are available per time slot (the downlink frame structure should be of type A).
  • the TFCI bits c 29 to c 06 of the punctured TFCI code word are accordingly distributed to time slots No. 0 to No. 5.
  • time slots No. 9 to No. 12 16 DTX bits are sent, while in time slot No. 13 two DTX bits are sent first, followed by TFCI bits c 05 and c 04 .
  • the remaining TFCI bits c 03 to c 0 of the punctured TFCI code word are finally sent.
  • the DTX bits not transferable after the transmission gap Time slots are assigned before the transmission gap.
  • the distribution can be arbitrary, whereby an even distribution of the DTX bits is advantageous is.
  • a special embodiment variant of the invention provides that in compression mode initially 30 bits of the TFCI code word are mapped onto the frame to be sent. Also be two originally punctured bits or two in normal mode (in normal operation or in non-compression mode) sending bits mapped to the frame to be sent. exceeds especially in the uplink the number in the corresponding compressed format available locations the limit of 32 format identification digits, so TFCI bits are repeated on the frame to be sent displayed; in particular, the TFCI bits, which are short after the transmission gap is sent, repeated on the frame to be sent is reproduced (repeated). This repeated mapping takes place in particular in relative to the first mapping of these TFCI bits in reverse order instead of.
  • the exemplary embodiments described using the uplink are also applicable to the downlink.
  • the present invention was previously described based on the use described in a mobile radio transmitter. Of course you can however, the invention also extended to mobile radio receivers which are corresponding to receiving and evaluating a processed according to the invention and then sent Signals are to be designed.
